The multi-talented star is so invested in his various projects such as acting, directing, teaching film classes and his various art exhibitions, he has very little time to rest, but his hectic lifestyle eventually takes its toll and he ''crashes'' in inappropriate places.

Quizzed if he ever goes to bed, he said: ''Some nights. I don't need sleep. And then you do enough of those [late nights] and you eventually crash - you know, odd places, on set, or in class, or wherever.''

The 35-year-old hunk's busy career leaves little room for a social life, but the 'Oz the Great and Powerful' star says he has found a way to incorporate socialising into his work by surrounding himself with like-minded pals.

He explained: ''Well, I mean, as far as my social life, I've just learned to work with the people I love.

''I enjoy working creatively with people much more than getting wasted with them. I guess I just used those hours at the bar to do other things.''

Despite juggling many different careers ranging from actor, director, professor, PhD student and artist, James still has some unfulfilled ambitions to cross off his list - including the stage.

He added to Britain's GQ magazine: ''I love theatre. I'm actually supposed to act on Broadway in 'Of Mice and Men'. So I think that's gonna happen. [And] I'd like to write a play.''
